Computers and Control Systems: Description and Operation
The air control valve (19), bypasses air around the throttle valve as instructed by the control unit. The air conditioning microswitch (4), closes when the A/C system is engaged, causing the control unit to increase the
idle speed.
The idle adjustment screw (26), allows for basic setting of the
idle speed.
